1-(2,3-Dimethylphenyl)ethanol

This substance is typically encountered as a clear, colorless to pale amber liquid at ambient temperature, characterized by a mild aromatic note. Its molecular composition is C10H14O, corresponding to a molar mass of 150.22 g/mol. The boiling point is approximately 240–245 °C at standard pressure, with an estimated density near 1.01 g/cm³. It is readily miscible with common organic solvents such as ethanol, acetone, and ethyl acetate, but exhibits only slight solubility in water and is practically insoluble in aliphatic hydrocarbons. The molecule possesses a secondary alcohol functionality adjacent to a disubstituted aromatic ring. It should be kept in wellsealed vessels away from strong oxidizing agents and stored in a cool, ventilated area to prevent oxidative degradation.

1(2,3Dimethylphenyl)ethanol is a secondary benzylic alcohol featuring a hydroxyl group attached to a chiral carbon adjacent to a 2,3dimethylphenyl moiety. The aromatic ring bears two methyl substituents in adjacent positions, which introduce steric crowding and electrondonating character, influencing the reactivity of the alcohol and the overall molecular conformation. The benzylic alcohol unit is a common motif in organic synthesis and medicinal chemistry, offering a site for oxidation, substitution, or further carboncarbon bond formation. The presence of the methyl groups enhances lipophilicity and can modulate interactions with biological targets. This compound serves as a versatile intermediate for constructing more complex structures, including pharmaceutical agents, fragrances, and agrochemicals, where the rigid aromatic core and the modifiable alcohol provide a handle for diversification.

Synthetic Intermediate in Pharmaceutical Research
This chiral alcohol is utilized as a building block in the preparation of various bioactive molecules, particularly those targeting central nervous system disorders. The benzylic hydroxyl can be transformed into ethers, esters, or halides, enabling attachment to pharmacophoric fragments. The adjacent methyl groups contribute to hydrophobic binding interactions and can influence the metabolic fate of derived compounds. Derivatives of this scaffold have been explored as potential antidepressants and anxiolytics.

Fragrance and Flavor Component
Due to its structural similarity to known aroma compounds, 1(2,3dimethylphenyl)ethanol finds application in the formulation of specialty fragrances. Its mild, slightly floral scent profile can be blended to create complex olfactory notes in perfumes, cosmetics, and personal care products. The compound's stability under typical formulation conditions and its ability to persist on skin make it valuable as a fixative or modifier in scent compositions.

Agrochemical Intermediate
In crop protection chemistry, this secondary alcohol serves as a precursor for synthesizing novel insecticides and plant growth regulators. The benzylic alcohol can be oxidized to the corresponding ketone or aldehyde, which then participates in condensation reactions to generate heterocyclic systems with potential biological activity. The dimethylphenyl moiety is found in several commercial agrochemicals, contributing to improved lipophilicity and target affinity.

Organic Synthesis and Catalysis
The compound is employed as a model substrate in studies of asymmetric synthesis and catalytic transformations. Its chiral center can be resolved or generated enantioselectively, providing access to optically active building blocks. Researchers utilize it to investigate oxidation, reduction, and C–H functionalization reactions, advancing methodologies for the construction of complex molecules. The rigid aromatic framework also makes it useful as a ligand precursor in transitionmetal catalysis.
